Having just listened to BBC radio4's saturday afternoon drama "Dead Girls tell no tales" on the 60th anniversary of the killing off of Grace Archer, it thought that the ARcher's intro music should count as about as English Trad as you can get, so maybe I can find an arrangement of this.
(Its actually a piece called "Barwick Green", a "maypole dance" from the suite My Native Heath, written in 1924 by the Yorkshire composer Arthur Wood)
